As their finales approach, Dexter
continue to grow on Showtime. And after last week's mild upset of Homeland outdrawing Dexter for the first time ever, the veteran serial killer drama rallied with its most-watched episode ever. And that 2.6 million viewer haul doubles as Showtime's biggest audience ever for an original series.
Dexter, averaging a robust 6.1 million gross weekly viewers across platforms during this season, topped its previous (and long held) record of 2.57 million viewers brought in during its season four finale.
